Question

How do you write the factor trees for 51?

Answer 1

51 is odd, but it can be divided by 3 (sum of digits divisible by 3)

Explanation:

So we get `51=3xx17`
And there it ends because `17` is prime.

`color(white)(0000)51`
`color(white)(000)"/"color(white)(00)"\"`
`color(white)(00)3color(white)(000)17`
